Labthink XLW(PC) Intelligent Electronic Tensile Testing Machine for Plastic & Packaging Films

Overview

The Labthink XLW(PC) Intelligent Electronic Tensile Testing Machine is a precision-engineered instrument designed for the mechanical characterization of flexible packaging materials and thin-film substrates. Based on the fundamental principle of uniaxial tensile testing—where a specimen is clamped between two grips and subjected to controlled axial displacement—the system measures force response via high-stability load cells and records displacement with integrated linear position sensors. This enables quantitative determination of key mechanical parameters including tensile strength, elongation at break, Young’s modulus, peel strength, tear resistance, seal strength, puncture force, and adhesion performance. The device conforms to internationally recognized test methodologies across polymer science, packaging engineering, and quality assurance disciplines, supporting both R&D validation and routine QC compliance workflows in regulated environments.

Key Features

• Class 0.5 force measurement accuracy per ISO 7500-1 and ASTM E4, ensuring metrological traceability and repeatability under GLP/GMP-aligned laboratory practices.
• Seven pre-programmed test modes—including tensile, peel, tear, heat seal, puncture, shear, and friction—eliminating manual setup errors and standardizing method execution.
• Extended 1000 mm crosshead travel accommodates high-elongation materials such as elastomeric films, hydrogels, and laminated structures without mechanical interference.
• Dual-load-cell configuration (50 N and 500 N options) allows optimal resolution across low-force adhesive testing and high-strength structural film evaluation.
• Seven discrete test speeds (50–500 mm/min) enable precise replication of industry-standard protocols (e.g., ASTM D882 at 50 mm/min or ISO 37 at 100 mm/min).
• Microprocessor-based control with PVC membrane keypad, large LCD display, and intuitive menu navigation reduces operator training time and minimizes input errors.
• Integrated safety architecture includes overload protection, mechanical limit switches, automatic return-to-start, and power-loss memory retention for uninterrupted test continuity.

Sample Compatibility & Compliance

The XLW(PC) is validated for use with polymeric films (PET, PE, PP, BOPP), laminates, foils, coated papers, nonwovens, medical tapes, protective films, rubber sheets, and fiber-based substrates. Its mechanical design and software logic comply with over 20 international and national standards, including ISO 37 (rubber vulcanized), ASTM D882 (thin plastic sheeting), ASTM D1938 (tear propagation), ASTM F88 (seal strength of flexible barrier materials), GB/T 1040.2 (plastic films), GB/T 12914 (paper and board tensile), and JIS P8113 (Japanese packaging film specifications). All test routines support audit-ready documentation required for FDA 21 CFR Part 11-compliant environments when paired with Lystem™ Laboratory Data Sharing System.

Software & Data Management

The proprietary Windows-based control software provides full test automation, real-time curve visualization (force vs. displacement), and post-processing analytics. It supports statistical evaluation of grouped specimens (mean, SD, CV%), overlay comparison of up to eight curves, trend analysis across batches, and customizable report generation with embedded metadata (operator ID, timestamp, environmental conditions, calibration status). Data export is compatible with CSV, PDF, and XML formats. Integration with Lystem™ enables centralized storage, role-based access control, electronic signatures, and automated backup—fulfilling ALCOA+ data integrity principles for pharmaceutical and food packaging QA/QC laboratories.

Applications

Typical use cases include: evaluating seal integrity of pouches and blister packs; quantifying peel adhesion of pressure-sensitive labels; measuring tear resistance of shrink films; validating tensile properties of biodegradable packaging; assessing puncture resistance of medical packaging substrates; characterizing elongation behavior of stretch wrap films; and verifying bond strength in multi-layer laminates. The system serves packaging engineers, polymer scientists, regulatory affairs specialists, and contract testing laboratories requiring reproducible, standards-aligned mechanical data for material selection, process optimization, and regulatory submissions.

FAQ

What standards does the XLW(PC) support for food packaging testing?
It fully complies with GB/T 1040.2, GB/T 12914, ASTM D882, ASTM F88, and ISO 37—covering tensile, seal, and peel performance of food-grade flexible packaging.
Can the instrument perform both tensile and peel tests without hardware modification?
Yes—seven built-in test programs are software-selectable; only grip type and alignment require physical adjustment per test mode.
Is the system compliant with FDA 21 CFR Part 11 requirements?
When deployed with Lystem™ and configured with audit trail, electronic signature, and user access controls, it meets Part 11 technical and procedural criteria.
What is the maximum specimen width supported?
Standard fixtures accommodate 30 mm wide samples; optional 50 mm wide grips are available for broader film evaluation.
Does the machine provide raw data export for third-party statistical analysis?
Yes—force-displacement datasets export in CSV format, preserving time-stamped point-by-point values for external regression modeling or SPC charting.
